Description

The Personal Solar Telescope (PST) is a Coronado innovation. The world's most popular telescope to observe the Sun. This 40mm diameter highly portable dedicated solar telescope features completly internal non-removable and student safe solar filtering optics with a 1.0 Angstrom hydrogen-alpha (HA) bandpass for great surface detail. The PST will show you the dynamic, ever changing prominences at the edge of the Sun as well as filaments and other surface details in amazing detail, all in the brilliant and distinctive red color of hydrogen-alpha light.

Study of the solar disk is now within the reach of the amateur astronomer. The PST represents the same technology and quality that goes into a SolarMax series telescope available to the new solar astronomer at the cost of some single premium eyepieces.

Features a 40mm diameter dedicated HA optical system with 30mm internal etalon primary blocking filter and incorporated focuser and bandpass fine adjustment controls and built in solar viewfinder. 400mm focal length, f/10 focal ratio, with Kellner 20mm eyepiece. Tripod not included.

Mounting options include use on a standard photo tripod (scope is threaded for a standard camera 1/4-20 mounting bolt), Infinity AZS, or the Meade DSM mount with computerized Autostar and GoTo technology. Open up a whole new world of astronomy with the Coronado PST.
